PATRICK J. MADDEN, OF CHICAGO, ILLINOIS.

URINAL.

Specification of Letters Patent.

Patented Nov. 30, 1915.

Application filed July 20, 1914. Serial No. 851,963.

To all whom it may concern Be it known that I, PATRICK J. MADDEN, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Urinals, of which the following is a specification.

The object of the present invention, stated generally, is of course, to provide a urinal of improved construction.

More particularly stated, one of its specific objects is to provide a urinal bowl of such construction that it, including all of its essential elements, maybe a unitary, integral structure, leaving, for its installation, nothing to be done, save only its proper connection with a watersupply pipe and a waste pipe, both of which may have any desired individual characteristics.

Still more particularly stated, one specific object of the invention is to provide means for insuring a refill, or after fill, as it is sometimes called, and this particular object I accomplish by so constructing and arranging the several elements of the bowl that the entire volume of the flushing water as it travels on its way to the bowl is first delivered into a chamber, from which it is conducted, through suitably arranged openings or passage, to the bowl proper, the hollow flushing rim and the jet opening which latter also serves to conduct to the trap the afterfill or refill water, after the supply of water to the chamber aforesaid ceases.

lVith these and other objects looking to the general improvement in the construction of devices of this class in view, the in vention consists in the features of novelty that are hereinafter described with reference to the accompanying drawings which are made a part of this specification, and in which Figure 1 is a plan view of a urinal embodying the invention, with portions shown in horizontal section. Fig. 2 is a front elevation thereof and of a waste connection, or trap, suitable thereto, the supporting wall or slab being omitted. Fig. 3is a vertical central section thereof on the line 33, Fig. 2, looking in the direction of the arrows. Fig. 4 is a vertical section on the line 44, Fig. 3, looking in the direction of the arrows, 2'. 6., from the back toward the front of the bowl. Fig. 4 is a detail section on the line 4 4 Fig. 4. Fig. 5 is a vertical central section of the upper portion of the bowl on the line 55, Fig. 4, looking in the direction of the arrow, 2'. 6., toward the sinister side as viewed from in front.

The material of which the bowl is made is, of course, immaterial, so far as the present application is concerned. It may be said, however, that the several features of novelty herein described are particularly applicable to urinal bowls that are 'made of earthenware, but this statement is not to be taken as a limitation of the invention to bowls made of any particular material as the invention is equally applicable to bowls of earthenware, metal or any other suitable material.

The bowl in its entirety is designated, 1. The receptor has the customary upright back, 3, and extending rearward from this back and conterminous therewith is a flange, 2, the rear edge of which is ground to a true plane and fits against the wall by which the fixture is supported. This flange, 2, is of sufficient depth to provide space for an annular chamber, 00, into which the entire volume of flushing water is introduced and from which said water is supplied to all of the various parts of the urinal, i. a, the receptor (directly) the hollow flushing rim, and the jet opening, which in the instance given alsoperforms the function of conducting the refill water to the trap. This chamber, 02, is located at the back of the receptor and the drawings show it as occupying a true vertical plane, but accuracy in this respect is not essential to the carrying out of the invention, the requirements of which are satisfied if it occupies'an upright, or substantially vertical plane. It is preferably divided into two compartments, 4 and 5, by a wall or partition, 6, having through it a restricted opening, 7 through which water may flow from one of said compartments to the other. The chamber, 419, is the result of a web, :0, which joins the flange, 2, and back, 3, upon opposite sides of and at suitable distances from their juncture as shown most clearly in Fig. 4 and this web not only enters into the construction of the chamber but is of material advantage as a strengthening device in the finished article and in eliminating the liability to warpage and distortion in the processes of molding and baking. It is the compartment, 4, of the chamber, a, which performs the function of a duct or passage for conducting water from the supply pipe performs the two functions of discharging a jet of water in the desired direction while the bowl is being emptied and a duct or passage for conducting water from the compartment, 4, to the trap while said comartment is performing the function of a refill chamber after the emptying operation is completed. Here it may be observed also that the shape of this compartment, 4, is not essential, in the broader aspects of the invention although it preferably takes the form of a duct or passage of uniform cross sectional area throughout, through which the water flows from the inlet pipe directly to the jet opening, a portion of the water flowing from the compartment, 4, of the chamber, a), through the restricted opening, 7, into the compartment, 5, in which it rises up to the level of the opening, 12, through which it passes to supply the fan spray, 14. In this connection it may be observed that the dam, 6, may be dispensed with, one of its purposes being to dam up or retard the flow of the water in the vicinity of the jet opening, 17 so that it will be forced from this jet opening at substantially supply pressure, while another of its purposes is to prevent the too rapid flow of water to the opening, 17, during the refilling operation.

It may here be stated that Fig. 4 of the drawings is correct but is nevertheless somewhat confusing or misleading because it shows the parts as viewed from the rear side of the bowlin fact, viewed in exactly the opposite direction in which they would ordinarily be viewed. This view point should therefore be borne in mind in considering the drawings. Nevertheless it may be here stated that while the drawings show a sinister discharge into the so-called refill chamber, this'is not at all essential as a reversal of these conditions would make no difference whatever in the accomplishing of the ultimate result aimed at.

A fragment of the water supply pipe is shown at 8. It passes through an opening formed through the back wall of the chamber w and its end is in open communication with said chamber. A water tight joint is formed'between' the end of this pipe and the bowl and this joint may be formed by any suitable means known to the art, but preferably the end of the pipe is flared, the open ing through the rear wall of the chamber 00 is correspondingly flared, a flared or wedge shaped packing-ring, 9, of any suitable elastic material is interposed between them and a nut, 10, is turned onto the threaded exteriorof the pipe, 8, so that when turned up it will bear against the back wall of the chamber :0 with a tendency to draw the pipe, 8, backward, and compress the packing-ring, thereby forming a water-tight joint.

In practice, water delivered from the pipe 8 and entering the chamber x will be deflected bya li'p,11, into the compartment, 4, of the said chamber which, in the instance shown in the drawing, is on the sinister side of the bowl as viewed from in front, but which as already intimated, may be other wise located and still be within the scope of the invention. Naturally the water thus admitted will seek the bottom of the compartment, .4, and pass through the opening, 7,

into the compartment, 5. Its level will gradually rise up in both of the compartments, 4 and 5, and the air above it will be expelled through ducts or passages, 12 and 16, into the customary hollow flushing rim, 13, of the bowl. At its highest point this hollow rim is'provided with a number of perforations, so disposed that they will discharge as many streams of water downward and rearward against the front surface of the back wall of the bowl in the form known in the art as a fan spray, as indicated at 14 in Figs. 1, 2, 3 and 5. It will, of course, be understood that the remainder of the hollow rim is provided atv intervals with properly disposed orifices or perforations, 15, for dis charging streams of water into the bowl in proper directions.

It may be here stated that while the duct, 12, communicates direct-1y with the hollow flushing rim and with the compartment, 5, of the chamber at, it communicates with the compartment, 4, through a transverse duct, 16, made through a web which is integral with the lip, 11.

Again recurring. to the operation of the device, as the flushing water is discharged from the pipe, 8, it will fill the chamber 00, and having reached the level of the ducts or passages, 12 and 16, it will flow into and r fill the hollow rim, 13, escaping through the openings, 15, into the bowl. Meanwhile, and before it reaches the level of the ducts or passages, 12 and 16, it will flow from the bottom of the compartment, 4, of the charm ber, as, out through a jet opening, 17, which is so disposed as to discharge a jet of water directly backward and outward through an outlet pipe, 18, which may be connected with the bowl in any suitable manner but which is preferably connected with it in the manner shown in the drawings and which is also shown, described and claimed in Letters Patent No. 897,914, which were granted to me September 8, 1908, the arrangement being such that a water tight joint is formed between the bowl around its outlet opening, 19, and the outlet pipe, 18. According to the present invention the outlet pipe, 18, communicates with the up-take leg of a trap, 20, the dam or overflow level of which, is

located at the level at which it is desired the refill water shall stand in the bowl or in the outlet pipe. This trap may be siphom'c or not, as desired. The drawings show a siof the discharge siphon-trap is in excess of the water supply opening, 12, or the opening, 7, so that in the operation of the device there will come a time when the siphonic action will break after which the water contained in the refill chamber will flow through the jet opening, 17, into the bowl and refill it to the desired depth, after the well known manner of devices of this character.

The chamber a; follows the general contour of the back of the bowl and is countersunk, or rather the flange, 2, projects rearward beyond the rear wall of the bowl and the countersink thus provided affords room for a supporting bracket, 21, which engages beneath an undercut shoulder, 22, formed at the back of the bowl, after the manner shown, described and claimed in Letters Patent No. 1,022,147 which were granted to me April 2, 1912, but no novelty is herein claimed for this construction and arrangement excepting as it involves the specificconstruction of the back of the bowl having within it the refill chamber following its general outline and the supporting shoulder formed directly on the refill chamber. a
